P0553 Ford Code - Power Steering Pressure Sensor Circuit High Input

Quick Answer

The P0553 Ford diagnostic trouble code (DTC) indicates an issue with the power steering pressure sensor circuit having a high input. Common causes include Faulty power steering pressure sensor: The sensor itself may be malfunctioning, causing it to send a high input signal to the ECM or PCM, Damaged wiring or connectors: Corrosion or damage to the wiring or connectors in the sensor circuit can disrupt the signal being sent to the ECM or PCM, ECM or PCM issues: Problems with the electronic control module receiving and interpreting the sensor signal can trigger the P0553 DTC. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0553 Ford Description

The P0553 Ford diagnostic trouble code (DTC) indicates an issue with the power steering pressure sensor circuit having a high input. In vehicles equipped with power steering systems, the power steering pressure sensor plays a crucial role in monitoring the hydraulic pressure within the power steering system. This sensor helps the vehicle's electronic control module (ECM) or powertrain control module (PCM) to adjust the power steering assist level based on driving conditions. When the sensor detects a high input signal, it means that the pressure within the power steering system is exceeding the expected range, leading to the triggering of this trouble code.

Common Causes of P0553 Ford

  1. Faulty power steering pressure sensor: The sensor itself may be malfunctioning, causing it to send a high input signal to the ECM or PCM.
  2. Damaged wiring or connectors: Corrosion or damage to the wiring or connectors in the sensor circuit can disrupt the signal being sent to the ECM or PCM.
  3. ECM or PCM issues: Problems with the electronic control module receiving and interpreting the sensor signal can trigger the P0553 DTC.
  4. Low power steering fluid levels: Insufficient power steering fluid can lead to high pressure in the system, triggering the code.

Symptoms of P0553 Ford

  1. Stiff or difficult steering: The power steering system may not provide the expected level of assistance, making steering more challenging for the driver.
  2. No power steering assist: In severe cases, the power steering system may fail entirely, leading to a complete loss of power steering functionality.
  3. Power steering fluid leaks: High pressure within the power steering system can cause leaks in the hoses or connections.
  4. Illuminated warning light: The vehicle's dashboard may display a warning light indicating a power steering system fault.

How to Fix P0553 Ford

  1. Diagnose the issue: Use a diagnostic scan tool to retrieve the trouble code and perform a thorough inspection of the power steering pressure sensor, wiring, and connectors.
  2. Replace the power steering pressure sensor: If the sensor is faulty, it will need to be replaced with a new, OEM-quality sensor.
  3. Repair or replace damaged wiring or connectors: Address any issues with the wiring or connectors in the sensor circuit to ensure a reliable connection.
  4. Clear the trouble code: Once the repairs are completed, clear the DTC from the vehicle's ECM or PCM using a diagnostic scan tool.
  5. Test drive the vehicle: After completing the repairs, test drive the vehicle to ensure that the power steering system is functioning correctly and that the P0553 DTC does not return.

Cost to Fix P0553 Ford

The typical repair costs for resolving a P0553 Ford code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, the cost of replacing a power steering pressure sensor can range from $150 to $300, including parts and labor. Additional costs may apply if there are issues with the wiring or connectors that need to be repaired or replaced. It's essential to check with local auto repair shops for accurate pricing based on your vehicle's make and model, as well as the extent of the repairs needed. Keep in mind that labor rates can vary, with average rates ranging from $80 to $150 per hour.

When is the Code Detected?
